集成React

1. 热调试

在React项目目录下安装Electron

npm install electron

修改package.json文件，增加或将已有的main属性值修改为main.js，在scriptes中添加"electron-start": "electron ."，最终配置文件如下：

{
  "name": "electron-react",
  "version": "0.1.0",
  "main": "main.js",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.16.5",
    "@testing-library/react": "^13.3.0",
    "@testing-library/user-event": "^13.5.0",
    "electron": "^20.0.3",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "electron-start": "electron ."
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

打开main.js,将

const { app, BrowserWindow, globalShortcut } = require("electron");
const path = require("path");
function createWindow() {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webContents: {
      openDevTools: true, //不想要控制台直接把这段删除
    }
  });
  win.loadFile("index.html");
}
app.whenReady().then(() => {
  createWindow();
  app.on("activate", () => {
    if (BrowserWindow.getAllWindows().length === 0) {
      createWindow();
    }
  });
});
app.on("window-all-closed", () => {
  if (process.platform !== "darwin") {
    app.quit();
  }
});

中的

win.loadFile("index.html");

修改为

win.loadURL("http://localhost:3000/")

打开两个终端，一个运行React

npm start

另一个执行

npm run electron-start

程序运行正常

2. 打包

默认情况下，homepage 是 http://localhost:3000，build 后，所有资源文件路径都是 /static，而 Electron 调用的入口是 file :协议，/static 就会定位到根目录去，所以找不到静态文件。在 package.json 文件中添加 homepage 字段并设置为"."后，静态文件的路径就变成了相对路径，就能正确地找到了添加如下配置：

"homepage":".",

随后运行build构建项目，构建完成后可以在build文件夹下执行index.html看看网站是否可以正确运行。

npm run build

如果可以。在main.js中将代码

win.loadURL("http://localhost:3000/")

更改为，即载入静态文件，载入URL可以作为热调试，打包时修改为静态文件。

win.loadFile("./build/index.html");

最终的文件

main.js为：

const { app, BrowserWindow, globalShortcut } = require("electron");
const path = require("path");
function createWindow() {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webContents: {
      openDevTools: true, //不想要控制台直接把这段删除
    }
  });
  win.loadFile("./build/index.html");
}
app.whenReady().then(() => {
  createWindow();
  app.on("activate", () => {
    if (BrowserWindow.getAllWindows().length === 0) {
      createWindow();
    }
  });
});
app.on("window-all-closed", () => {
  if (process.platform !== "darwin") {
    app.quit();
  }
});

package.json为：

{
  "name": "electron-react",
  "version": "0.1.0",
  "main": "main.js",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.16.5",
    "@testing-library/react": "^13.3.0",
    "@testing-library/user-event": "^13.5.0",
    "electron": "^20.0.3",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "electron-start": "electron ."
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "homepage":".",
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

目录结构为

之后的打包和平时的打包一样即可。
